摘要
青藏高原是我国崩塌、滑坡、泥石流等自然灾害最严重的地区之一。以西藏G4218高速公路白衣错~莫格段沿线地质灾害为研究对象,通过详细野外调查,系统研究沿线崩塌、滑坡、泥石流的危害特点,查明公路沿线灾害分布,分析其对山区公路的影响,归纳灾害形成条件和活动特征。针对沿线不良地质现状,对其发展趋势进行了有益的探讨,为山区公路灾害治理和选线提供有效的基础参考。
Tibetan Plateau is one of the most serious debris flow hazard regions in China.Taking the geological hazards of G4218 as the study object,after field investigations,the damage characteristics such as collapse,landslides and debris flow are systematically studied,and hazards distribution along the G4218 are found out,then the influences to the mountainous highway are analyzed,and finally,the forming condition and activity features are classified and summarized.The development tendency of unfavorable geology is discussed along the highway,which provides some reference for the disaster prevention and determination of highway route.
